[solved]tyre pressures for mixed tyres?

Can anyone advise me on correct tyre pressures? I picked up my cb 500s yesterday and rode it home 88miles. It has an avon roadrider on front and a bridgestone bt 45 on the rear. Checked pressures this morning and the guy I bought it off had the front at 38psi and rear at 40. Honda say 29 and 33, however I'm aware that tyre manufacturers say different. Just a bit confused as mixed tyres and front felt a bit 'harsh' to me on the way home, particularly on motorway bits. Any experience/advice greatly appreciated
